Course Description

This is the first semester of Intermediate Algebra. Includes an introduction to the study and application of quadratic, radical, exponential, and logarithmic expressions and functions. Working with real data and the mathematics of curve fitting will be developed using a graphing calculator.

No textbooks are required because the course is self-taught on MyOpenMath.com, a collaborative platform with the best free, open textbooks, and personal help available when necessary.  The format includes the opportunity for unlimited practice with multiple versions of problems and occasional video supplementation.   If the student gets stuck, he simply presses the help button to email his work to the instructor, who responds as a personal tutor. 

Our AP certified math instructor also serves as an adjunct professor at several colleges, including Johns Hopkins University.  MyOpenMath.com is the platform he uses to teach online in all of these venues.  Students should contact the instructor during the first week of the term for a personal orientation to the platform.
